Advanced Visualization Branch

Nursing research has the capacity to inform the design of effective interventions for people facing homecare challenges through understanding the ways in which environments support or interfere with self-management.

The Advanced Visualization Branch (AVB) develops and evaluates advanced visualization environments, particularly immersive virtual reality (VR), to study in depth the ways people carry out instrumental activities of daily living, the impact of cognitive challenges and distractors on performance, and the manner in which observations may complement or supplant self-report indicator of performance.

AVB Staff Profiles

Dr. Patti BrennanAdjunct Investigator: Dr. Patti Brennan

The AVB lab develops interactive virtual reality simulations that present health information to patients with a variety of complex health conditions. These simulations enable patients to rehearse problem-solving behaviors to foster improved health outcomes within home-based care environments. This research also seeks to define methodologies for AR/VR technology as a health tool to aid disease-management nursing strategies in the transition from acute care settings to outpatient environments. Additionally, this research seeks to identify recommendations for how to best deliver this type of technology to patients.


Denise Goldsmith

Current Work

Denise Goldsmith has extensive experience as a clinical informatics specialist. Her research has focused on using innovative technology to improve the care of patients in both hospital and home settings. Denise provides a nursing foundation to the AVB and connects the team with experienced home care nurses who identify patient's self-care management issues important to our work. She develops and validates the clinical scenarios chosen to study in our VR environment. Previous experience includes:

  • Chief Nursing Informatics Officer, Brigham and Women's Hospital, Boston
  • Director, Clinical Informatics and Chief Privacy Officer, Clinician Support Technology, Boston
